DEMOUNTABLE WHEEL.

Application filed September 8, 1926. Serial No. 134,282.

vided with an equal number ot openingst-oy receive the studstherethrough. It is somewhat of a task to Valign the openings with thestuds, and a task that requires a comparatively great length ottime inscrewing the nuts home on tliegthreaded studs or bolts, and a similarlength of time in unsci'ewing the nuts when the wheel is to be removed.With my present invention I propose to provide the hub flange with onlytwo headed studs and a single bolt, the same being mounted andassociated in a manner whereby the screwing of the single nut on thebolt will not only exert a binding Aaction against the disc wheel,`butwill cause the heads ot the studs to be brought into frictional contacttherewith so that the wheel is easily, quickly and firmly secured on theliiib flange.

A stillxfurther object is the-*provision ot' a means tor securing a.disc wheel to the hub flange of a vehicle, that comprises aswingable'plate mounted Yon the rear face of the Harige and carryingspaced studs which may be `integrally formed with or provided withremovable heads, and which studs are pivotrally associated withtheplate. The said plate is also provided with a pivotally connected boltand the disc wheel `is provided with lsuitable openings, to receivetherethrough .the studs and the bolt. A nut is screwed home on the bolt,and contacts with and eants the plate to bring the heads ot the studsinto tight frictional contact with the outer tace of the disc wheelwhereby the disc `wheel may be easily and quickly secured onV the huband as readily removed therefrom when occasion requires.

l/Vith the above broadly stated objects in View and others which willpresent themselves asthe nature ot the invention is better understood,the improvement further consists in certain novel features ofconstruction, combination and operative association of parts, one ofanumber of satisfactory einbodiments et which is disclosed by the ae=drawings.

Figure 7 is a sectional view approximately on the line 7-7 of Figure 6.

A tire carrying discv wheel of the ordinary .Construction is disclosedby the drawings and 1s indicated by the numeral 8. In one torni of myinvention the wheel 8, above andV atthe opposite sides of its centralhub re-Y ceiving opening 9, is provided with key-hole slots. 10-10, andcentrally below the hub opening 9 the disc wheel is provided with a boltopening 11. The hub 12 is ot' the usual construction, and vis attachedto the spindle or shaft in the usual manner. The hub is provided withthe usual flange 13, andv this flange, at the opposite sides of the hubhas on its inner face ears 111. I

The numeral 15 designates the Swingable plate that constitutes one of'the important `features of my invention. The plate is centrally formedwith an opening 16 through which the hub 12 is received, the said plateat the opposite sides of the opening being formed with ears 17 disposedin lapping relation with the ears 141, and through these aligining earsthere is passed a pivot 1S. It will thus be noted that the plate 15 isswingably `mounted 0n the hub flange 13. l

preferably. reduced., t at. is, 'the said plate has its edges cutinwardly and merge into a straight lower portion 24. The portion 24 isprovided with a pair of ears 25, between which ears there is receivedand pivoted the rounded headed portion of a bolt 26, the said boltpassing through an elongated opening 27 in the part 24 of the plate 15.

It is to be noted that all of the ears on the plate l5 extend in thesame direction as do the studs 22.

In this embodimentof the improvement the studs 22 have outer disc-likeheads 28.

The wheel 8 is arranged so that the heads 28 of the studs 22will passthrough the widervpassages of the key hole slots 10. The wheel is thenmoved so that the stu-ds are received in the restricted passages ofthekey-hole slots. or openings lOand the bolt 26 is received through theopening 11. A nut 29 is screwed on the bolt 26, and forces a lock washer3() against the outer face of the disc wheel 8. The screwing home of thebolt will swing or cant the plate l5 so that the heads 28 of the studswill be brought' f mount, regardless of the jars to which the same issubjected when traveling over uneven road surfaces, and the wheel cannotybe disassociated from the hub until the nut .with the said plate. Theplate, for distinction, is indicated by the numeral 3l and carries atits upper corners studs 32. The studs may beloosely mounted for slightswinging on the plate but are held from direct longitudinal movementthereon. These studs have their upper ends provided with annular'depressions 33, and the said studs are designed to pass freely throughround openings in the disc wheel 34. The bolt 35,-,carried by the saidplate 31, also passes through a-'round opening below and centrally withrespect to the openings that receive the studs 32 therethrough. When theparts are so arranged I pass over the projecting end of each stud 32V ahorseshoe washer 36. rIhe :central portion of each of these washers isturning of the `nut 38, of course, compresses the loclr washer so that alocking engagement is thus produced between the nut and the disc'wheel.The modied form of my improvement has all of the advantagesvof the Erstmentioned forni. It is, of course, to be understood that the wheel is*supported on the hub and that the means herein de scribed serve mainlyfor locking theV wheel on the hub, and thus the studs and bolts of myimprovement are not subjected to -unnecessary strain. Dise wheels embodya natural resiliency, and, therefore, I maydispense with the employment*of the lock washersy inasmuch as there will be at all times africtionalengagement between the nuts which engage the bolts and the wheel andsuch engagement will prevent -the'unscrewing of the bolts. To assist inthis the threads of the bolt may be cut so that the turning of the wheeland the frictional contact of the said wheel withl the cuts will have atendency to screw the nuts home.

The simplicity lof my construction, the

ease in which the same may be operated to lock or release a wheel fromahub'will, it is thought, be fully understoodand appreciated by thoseskilled inthe art to which suchinvention relates. Of course, I do notwish to be limited to the precise details of construction herein setforth and, therefore, hold myself entitled to all suchl changes andmodifications therefrom as fall Vwithin the scope of what I claim',provided ksuch` changes ,do not depart from the vspirit or sacrifice anyof the advantages of the invention.

Having described the invention, I claim:

`l. Means for securing'a wheel onta-hub, comprising elements carried bythe hub and passing through the wheel for Vgripping engagement therewithand means Vpassing through and adjustablyr engaging the wheel andassociatedwith the first elementsto-impart a longitudinaly movementthereto to bring the same into tight gripping engagement with the wheel.j Y,

2; Means for securingla vwheel on the hub thereof, comprising aswingable member on the hub, wheel engaging gripping elements thereon,and adjustable means associated with said swingable member passingthrough and engaging thee wheelv for canting the swingable member tobring the gripping elements into gripping engagement with the wheel.

8. Means for removably securing a wheel on the hule therefor, comprisinga plate swingably mounted on the hub, studs carried by the plate andreceived through the wheel, heads for the studs, a bolt member disposedaway from the studs and received through the wheel, and a nut screwed onthe bolt for swinging the plate to bring the heads of the studs and thenut in tight frictional contact with the wheel.

4. The combination with a disc vehicle wheel, and a flanged hubtherefor, said Wheel having spaced key hole slots therethrough, and abolt opening below the slots, a plate pivotally supported on the hubflange, headed studs carried by the plate, and designed to be receivedthrough the key hole slots, a bolt member carried by the plate to bereceived through the bolt opening in the wheel and a binding nutdesigned to be screwed on the bolt when the studs have their Shanks.

received in the restricted openings of the key hole slots, whereby toswing the plate to bring the heads of the studs into tight frictionalcontact with the wheel.

5. Means for securing a wheel on the hub therefor, in which said wheelhas a pair of spaced key hole slots,and a bolt opening disposed awayfrom but between the slots and further wherein the hub is provided witha flange that is formed with ears,

a plate having an opening to receive the hub therethrough, ears on theplate pivotally secured to the ears of the hub flange, other ears en theupper corners of the plate, headed stud members passing freely throughthe said corners of the plate and pivotally secured between the lastmentioned ears, said plate having its lower end reduced and, pro-videdwith spaced ears, a bolt member Ypassing freely through the plate andpivably supported on the hub and passing.

through the wheel for gripping engagement therewith, a bolt memberassociated with ysaid swingablel means and also designed to pass throughthe wheel, a nut screwed on the bolt for influencing the swingablemember to bring the .elements into tight gripping engagement with thewheel and said nut, by virtue of its frictional contact with the vheel,being held from unscrewing on the olt.
